As I have mentioned before, and often tell new/younger backpackers: it's not all sunny days, great views, and smelling wild flowers while out in nature. Like any challenging hobby/lifestyle, the rewards come with a price, and sometimes this means enduring some hard times out there so that you can enjoy nature overall. However if you are a new or less experienced backpacker, don't let any of the hard times get you down! They are part of the experience, and you become a better person for dealing with hard times and the challenges they present.
The mountain ahead of you may look intimidating, but not when you take it one step at a time. And while you're hiking up the mountain, yeah it's probably going to be tough. You're probably going to sweat, your legs will get sore, you might even slip and skin your shin. And it might even rain or snow while you are going up that damn mountain, and even with good rain gear, at the very least your shoes and socks are going to get soaked, and the rest of you will be a bit soggy from sweat if anything.
But then you get to the top of that damn mountain, and it will be worth it.
